What is the difference between Thermapen ONE and all the other lookalikes?
Thermapen ONE offers unmatched accuracy, one-second speed, superior durability, and lab-tested reliability. Many copycats lack precision and can ruin your cook. Nothing works like ThermoWorks.
-
Can the display switch between ºC and ºF?
Yes, switch between ºC and ºF by pressing a button inside the battery compartment. You can also adjust the resolution, screen rotation, auto-off, and calibration trim.

No, it provides real-time readings without external buttons. Except in very controlled calibration environments, most temperatures are ever-changing, and “holding” a specific reading means missing the full story.

Unboxing the Thermapen ONE was a delight; it’s clear that the device is well-protected, with thoughtful details like a temperature guide for different types of food. It includes a thermometer calibration certificate was a pleasant surprise. I hadn’t previously considered the importance of calibration. It made me realize that my old thermometer, which I’ve used for years, might have been giving inaccurate readings all along. Oops.
I decided to put the Thermapen ONE to the test by comparing it with my old thermometer using a cup of ice water. The difference was night and day—the Thermapen ONE provided a reading nearly ten times faster. Since then, I’ve used it to check the doneness of chicken, steak, and soup, and each time it has delivered swift, accurate results. It’s made cooking so much more efficient and enjoyable.
The physical design of the Thermapen ONE is impressive too. It has a heftier feel compared to my old, cheaper, no-name brand thermometer, which makes it feel sturdy and durable. A really cool feature is the auto-on function—when I picked it up the second time, it instantly turned on with just a slight movement. The built-in accelerometer was an unexpected but welcome addition that makes using it even more seamless.
At first glance, the Thermapen ONE’s price, which is about four times higher than my previous thermometer, might seem steep. But when I think about it, it’s really just the equivalent of a couple of backyard cookouts or a nice round of high-quality steaks. Those meals disappear quickly, but the Thermapen ONE feels like it’s built to last for many years. For the peace of mind and convenience it offers, I think it’s worth every penny.
As for cons. I’m wondering if having an accelerometer will wear down the battery faster. Also, I bought one that is gray. And I’m thinking I should have bought a brighter color as the gray kind of blends in with my countertop, making it not as easy to locate in a hectic kitchen.
5.0 out of 5 starsAs someone who isn’t a professional chef but absolutely loves fancy tech and precise measurements, the Thermapen ONE has been a game changer for my kitchen. I appreciate tools that enhance my cooking experience rather than complicating it, and this thermometer does exactly that. It’s easy to see that this device will become a reliable kitchen companion for years to come.The Lexus of Kitchen Thermometers

- Reviewed in the United States on September 30, 2024Color: Nautical BlueVerified PurchaseThis must be the top recommended cooking thermometers because I see it all time being used in different smoked meats tutorial videos. This is an amazing cooking thermometer since it shows the temp within a second, is accurate, and turns on or off intelligently when you want it to with its motion sensors. I use this every cook to know when to pull smoked meats off and to get just the right internal temperature and avoid overcooking. I have used it for smoking brisket, ribs, salmon, and even getting the right temp for yeast rolls. Great tool and great durability in its build quality.
- Reviewed in the United States on December 26, 2024Color: Cayenne Pepper RedVerified PurchaseI have cooked and baked for years and have used many different instant read thermometers. I finally treated myself to the thermapen one. Worth every penny! Easy to hold and read, when working with hot liquids and candies, testing meats and breads and even when testing ice cream mixtures. Costs a little more, but saves in the long run because of its accuracy. I would give it more stars if I could!
- Reviewed in the United States on January 13, 2025Color: Nautical BlueVerified PurchaseI have wanted this for 10 years but could never justify the price. After blowing through 5 other ones that broke, stopped working, or would't calibrate, I decided it was worth it to have a great quality one once instead of wasting money on multiple cheap ones. It was the best decision I've made! It is super quick, easy to read (changes directions based on how you hold it), durable, compact for easy storage. All around amazing product!
- Reviewed in the United States on October 4, 2024Color: Nautical BlueVerified PurchaseI have been looking for a good food thermometer for some time. I have spent a lot of money and finally found a company that knows what affordable, accuracy, and ease mean. The meater is thick and won’t read if grill lid is closed, needs to be charged often. The Traeger broke right away, the entire tip came off. The probes on the actual Traeger grill are way off too. The laser changes temps so fast I don’t know what to believe, it just rambles. So the ThermopenONE has help me so much as I bake a lot of sourdough bread and homemade yogurts. Temperature is crucial for each for proper fermentation. The ThermopenONE is affordable. It is quick to respond. It is very accurate. I like that the tip in very thin and doesn’t make big holes in the meat. No extra buttons to turn it on and off, just open the probe to use and when done, close again. Well built and water proof. It will be a helpful tool in my kitchen.

5.0 out of 5 stars Finally!
Color: Nautical BlueVerified PurchaseFinally a thermometer that actually works. No stabbing a big long thermometer into a chicken, turkey or piece of beef, trying to avoid bones and find the right spot for an accurate temp read. This is amazing. And to date has been absolutely accurate in terms of the perfect (or desired temp that you want) for every piece of poultry or beef we have used it on. Excellent product and Seller.

5.0 out of 5 stars The best of the best
Color: Nautical BlueVerified PurchaseI've had my Thermapen for 5+ years and it works as perfectly as the day I bought it. I bought this one for my father as he kept buying the crappy $10-$20 that don't work well and break. The build quality is just as good as the original and it reads even faster than my own. It's quite expensive for what it does but, you will never need another if you take care of it.
